This is an LED based Aquarium Light. It consists of a sheet of plexiglass with holes drilled in it to accommodate LEDs facing downward into the tank. The circuitry is above the plexi and will be waterproofed with silicone/hot glue later on. The power supply can be any transformer that you have kicking around. I used a 9.0VDC 800mA clock radio transformer.
The idea of this is to:
1) Reduce the cost of lighting your aquarium
2) Lower the heat generated by lighting
I am in no way responsible if anything goes wrong, and as with any electronics, there is a certain amount of risk involved.
I would not recommend using this on a planted tank because LED's do not have the proper spectrum.
